Imports a space time vector dataset from a GRASS GIS specific archive file.

t.vect.import --help
t.vect.import [-eoc] input=name output=name  [basename=string]  directory=name  [title=string]   [description=string]   [location=string]   [--overwrite]  [--help]  [--verbose]  [--quiet]  [--ui]



Extend location extents based on new dataset


Override projection check (use current location’s projection)
Assume that the dataset has same projection as the current location


Create the location specified by the "location" parameter and exit. Do not import the space time vector datasets.


Allow output files to overwrite existing files


Print usage summary


Verbose module output


Quiet module output


Force launching GUI dialog


input=name [required]

Name of input file

output=name [required]

Name of the output space time vector dataset


Basename of the new generated output maps
A numerical suffix separated by an underscore will be attached to create a unique identifier

directory=name [required]

Path to the extraction directory


Title of the new space time dataset


Description of the new space time dataset


Create a new location and import the data into it. Do not run this module in parallel or interrupt it when a new location should be created


t.vect.import imports a space time vector dataset archive that was exported with t.vect.export.


Optionally a base map name can be provided to avoid that existing vector maps are overwritten by the map names that are used in the STRDS archive.

The directory is used as work directory in case of import but can also be used as a data directory when using GML for the data exchange.


In this example, five vector maps are created and registered in a single space time vector dataset named random_locations. Each vector map represents random locations within the boundary of the state taken at 1 month intervals. The space time dataset is then exported and re-imported.

db.connect -d
for i in `seq 1 5` ; do
    v.random output=map_$i n=500 restrict=boundary_state@PERMANENT
    echo map_$i >> map_list.txt
t.create type=stvds temporaltype=absolute \
         output=random_locations \
         title="Random locations" \
         description="Vector test dataset with random locations"
t.register -i type=vector input=random_locations \
           file=map_list.txt start="2012-01-01" increment="1 months"
t.vect.list random_locations
t.vect.export input=random_locations output=random_locations.tar.gz \
t.vect.import input=random_locations.tar.gz output=new_random_locations \
              basename=new_map directory=/tmp
